Computer Won't Come On - Weird Issue

I have an eMachine 3110 & when I power it on, the fans all spin & the CPU fan spins spins as well. I have replaced the motherboard & CPU & it does the same thing. I also put a spare power suppy in it with no luck. Now I am down to replacing the RAM. I took the RAM out & though it would produce some type of beep cope it does not. Also, the weird part of it, I can taake the RAM out & leave it off for a few minutes then place it back in, sometimes the computer will come on & went to the desktop & another time I could not get past the BIOS.....Now, when I tuen it on, the CPU fan spins at a loud very fast rate....what are your thoughts on this???

Possible virus.

Are you able to boot into safe mode or maybe put the drive into another PC and run a virus check?

No, sometimes it will POST & sometimes it won't

Are you able to put another drive into that PC to see how it boots?

Seems that you have replace everything apart from the drive.

I have seen a virus cause fast spinning fans and non boot before.

That is my hunch

Can you try booting from a Linux disc? Most Linux install discs are "live" installs which run in RAM before actually installing to the HDD. This way you can test-out hardware before committing to the install. It also provides a way to boot without doing so from the internal HDD. I use Ubuntu Linux.

Hmmm...so you are saying if I can boot from a Live Linux CD, it is probably the hard drive or something on my HD (like a virus) causing my issue?

Also, if it does not boot from the Live Linux CD, it is probably the RAM? or some other hardware issue?

Jason Watkins

If it won't complete POST then it is some kind of hardware issue (as you probably know). The beep code, if any, would hint as to what that problem is. Ubuntu will run on as little as 1GB of RAM. Don't get me wrong, it'll be slow, but it'll run. The Live-CD can skip the HDD as a boot device and any problems with it.

remove all plug in and disconnect all peripherals except monitor see if it turns on. Then just connect KB retry, then mouse, etc adding only 1 device at a time to see what device / peripheral may be loading the PS down.

You have tried a different monitor haven't you.

Note tmoore1962's comment just above. If his troubleshooting advice doesn't work then you may have two dead motherboards.
